The means consists of a threaded rod 3|, a stop nut 32 engaging with the rod 1-H and a clamping nut 33 which also engages with rod 35. The latter extends up through the opening 38 in the spreader 25. The nut 32 abuts against the lower face of the part #8 of the spreader IS. The nut 33 is to abut the upper face of the part N3 of the spreader Q6. The nut 32 provides for elevating and lowering the spreader is relative to the element 55.

Connected to the lower end of stem M by a coupling M is one end of an oil feed line 35 leading from a source of supply not shown.

The form of burner shown in Figures 1 to 6 is of the circular type, whereas the burner shown in Figures 9 to 11 is of the oval type, and with reference to Figures 7 to 11, the burner illustrated thereby is generally indicated at 35.

The burner 35 includes a combined fuel trap, flame spreader and fuel distributing pipe carrier element 35 which is of oblong contour and of concave contour in transverse and lengthwise sections, a tubular oval shaped burner element 37 which has its ends and sides arranged inwardly with respect to the ends and sides of the carrier element 35, a cruciform shaped fuel distributing pipe 38 arranged within the element 37 and a flame spreader element 39 of oval contour of greater length and of greater width than the carrier 36.

The body portion 40 of the carrier 36 is of substantially dished or saucer-shape form and provided with an opening 4i intersected by the longitudinal and transverse medians of the carrier. Secured to the edge of the opening 3! is a vertically disposed sleeve 32 having its top edge formed at equi-distant spaced points with semi-circular cut-outs 43 in which are seated the branches of the fuel distributing pipe 38. The latter is suitably secured to the edges of the cut-outs l3 by welding or otherwise. The sleeve 42 is of a height to extend above and correlates with the body portion 40 to provide a fuel trap 52 The sleeve 32 forms the inner wall of the trap 52.

The element 31 is formed of a tubular body 44 of oval contour and has its upper face at its sides and ends formed with spaced circumferentially extending grooves 45 of the same form as the grooves 25. The top of body ii is provided with a row of spaced ports 66 of the same arrangement with respect to the grooves 45 as the ports 26 are arranged with respect to the grooves 25.

The pipe 38 is formed of four branches 4?, 48, 49 and 50. The branches 3?, 433 are disposed in inner endwise aligned relation. The branches 9, 50 are arranged in inner endwise aligned rela tion. The branches ll, 42 are of greater length than the branches 49, 50. The inner ends of the branches merge into each other. The outer ends of the branches 47, 48 merge into the inner sides centrally thereof is provided with of the ends of the element 31. The outer ends of the branches 49, 5! merge into the inner sides of the sides of th element 37. The outer ends of the branches of the pipe 38 open into the body M of the element 31.

The spreader 39 is formed of a dome shaped part 5i merging at its bottom into an endless outwardly directed flat flange 52. The part 5! of the spreader 39 is formed with a pair of spaced aligned openings 53 each for the passage of an upstanding adjustable supporting means for spreader 35. The supporting means are indicated at 54 and are of like form and each consists of a vertically disposed threaded rod 55, a stop nut 56 engaging with the rod. The rods extend upwardly through the openings 53. The lower ends of the rods are anchored to the branches W, 48 of the fuel distributing pipe 38.

The nuts 55 bear against the inner face of the part 5i of spreader 39. The nuts 51 bear against the outer face of the part 5! of the spreader 39. The function of the nuts 56, 57 is the same as the function of the nuts 32, 33 respectively.

Connected to the points of mergence of the branches 41, 48, 49 and 50 of the distributing pipe 38 is the upper end of a depending tubular fuel intake stem 38 which passes through the sleeve 42 to a point below the latter. The stem 38 is disposed axially of the sleeve 42 and has its lower end connected by the coupler 38 to a fuel delivery line 58 leading from a source of supply not shown.

The connection of the fuel distributing pipe to the carrier, to the burner element and to the oil feed or supply line provides for the suspension of the carrier and burner element.

The burner elements are endless. As to the operation of the burner, it will be assumed that the burner is inactive and when in such condition, the carrier element is to receive a body of liquid fuel which is ignited to cause the combustion of the fuel fed to the openings in the burner element whereby a continuous operation of the burner is had until the fuel supply is cut off.

The liquid fuel is supplied through the openings and directed by the grooves of burner element into the carrier element.

The carrier element I3 or 36 is held up by any suitable means, preferably from the grates in a stove, and upon the grates is placed a small body of clay, but the center of such body is formed with an opening for the draft to come up through, at this point an element l3 or 36 is placed on the clay body. The burner element is then positioned relatively to the element l3 or 36, and in this connection, the pipe I 4 is seated in the top of sleeve 22 and with its intake stem depending through the sleeve, or the pipe 38 is seated in the top of sleeve 42 and with its intake stem depending through sleeve 42. The stems of the pipes M, 38 are to be arranged to extend down through the central opening in the clay body referred to and one connected to the feed line 34 and the other to the feed line 58.
